Hurtingdad, I'm sorry to hear the news too. Oh boy!!! I'm almost speechless, but I just want you to know I care, and am praying HP gets you through this.
I know it hurts and each time you hope this is the time he will stick with it, recovery. I know you can't help but feel disappointed. It's like watching someone take a turn for the worst. Thank goodness you don't see him right now.
May HP hold you, son and his mother in His loving care.
